• IntraLase Femtosecond Laser (Disposable Patient Interface): A sterile PI single-use procedure pack is opened for every procedure. No cleaning and sterilixation issues, no blade induced corneal trauma.
• Joystick: Joystick controls X, Y and Z movement to easily align the laser delivery system.
• Ergonomic Design: The IntraLase Femtosecond Laser was designed to complement most excimer laser systems and maximise surgical efficiencies. By slightly rotating the existing excimer treatment bed, the patient may be easitly aligned beneath teh IntraLase FS Laser for the IntraLASIK procedure.

The IntraLase FS laser creates the flap under very low vacuum, delivering the laser energy directly to the stromal layer of the cornea through a disposable glass lens. The outer surface of the cornea suffers no trauma, and the procedure is completely painless. In testing, grater flap stability as well as a high degree of accuracy in both the depth and size of the resections has been demonstrated.

What is the difference between a femtosecond laser and the excimer laser commonly used in vision correction procedures? The word femtosecond refers to the pulse duration of the laser as it impacts the cornea. The IntraLase FS laser uses a rapidly fired, very short pulse with a spot size of only 3 microns. This enables the IntraLase FS laser to apply less energy to the corneal tissue with micron range accuracy. Excimer lasers use a 193 nm wavelength which is absorbed at the cornea's outer surface, immediately ablation tissue upon contact.

The IntraLase FS laser uses a long wavelength (1053 nm) that is not absorbed but instead can pass through the cornea with absolutely no effect on tissue until it reaches the pre-programmed target. The Intralase FS beam is optically honed into a 3 micron spot size and precisely delivered via IntraLASIK computer software to the prescribed intracorneal location. The laser pulsed are placed close together to define precise subsurface areas of photodistruption.
